Even cheap triple-axis magnetometer ICs, like those used in some smartphones could give interesting data if you put them in stable temperature conditions. Lot of such modules on aliexpress for a buck, not very sensitive, but definitely enough to detect serious disturbances in Earth magnetic field.
Didn't find any signs of weakening Earth magnetic field.

There is DIY Earth field magnetometers projects like http://avtanski.net/projects/magnetometer/design.html , pretty interesting thing to build, may be I will spend some weekend on it.

You'd think Yolanda would know better than to pick up negroes
I've read a bit about the particle bombardment we face as the field weakens, but nothing about specific ways to mitigate the damage.

This study may be of interest, although any conclusions or recommendations will obviously have to adhere to official government policy.
